BACKGROUND

There are limited options utilizing a gravity fed, pour over coffee making method to efficiently brew multiple servings of coffee while camping or recreating outdoors. Commonly, outdoor coffee makers can only make a limited number of servings in one brew cycle or are designed to serve just one individual. These devices are inefficient for brewing coffee for both larger and smaller groups or for individuals desiring more than a few cups of coffee without having to repeat multiple steps and brew cycles. Other devices like percolators and press pot coffee makers can produce an undesirable astringent cup of coffee because their brew techniques can be prone to either under or over-extracting the coffee. Moreover, these devices either require a heat source to keep the brewed coffee hot or lack the insulation necessary for ensuring beverages stay hot or cold for extended periods.

Camping coffee pots, percolators, and press pot style coffee makers are often comprised of mechanical parts that are susceptible to bending or braking, making them insufficiently durable for extended use outdoors. Moreover, thoroughly cleaning these coffee makers requires cumbersome removal of parts and then reassembly that provide additional opportunities for damaging their parts. Several types of outdoor coffee systems require bulky propane cylinders, heavy stovetops, or electrical components in order to heat the coffee or boil the water that are difficult to transport, prone to failing, and inapt for backcountry travel. Although some beverage dispensers or water coolers provide means for insulating cold beverages, they are limited to just insulating cold liquids and do not provide a means to keep beverages like coffee or tea hot or offer brewing capabilities.

Therefore, there is a need for a durable outdoor portable brewing device that efficiently makes large quantities of great tasting coffee utilizing a pour over brewing method, while advantageously holding and insulating both hot and cold beverages for consuming immediately or later, thus reducing or eliminating some of the problems discussed above. Disclosed herein are different embodiments of such device.

SUMMARY OF THE INVENTION

The present embodiment in general terms concerns a portable device for making coffee or tea and insulating any hot or cold beverage. The device utilizes a gravity fed brewing method for making pour over style coffee or tea in quantities to serve large and small groups while in the backcountry or at home. In accordance with one embodiment, an insulated multifunctional portable beverage brewing device and method for making the same comprising, a vessel that houses an insulation chamber and an interior liner wherein a removable filter apparatus rests. The insulation chamber surrounds the interior liner for keeping beverages either hot or cold. A detachable lid covers the vessel opening and provides access to the interior vessel when removed. A removable filter apparatus capable of holding and brewing large quantities of brew mixtures within one brew cycle. The gravity fed pour over brewing method naturally filters and fully extracts the ground coffee or tea, without under or over extracting the desired brew mixture. A filter seal attaches around the top edge of the filter apparatus to both seal the filter into place within the interior liner and to shield materials from escaping over the filter apparatus into the bottom of the interior liner reservoir. A controlled dispensing device attaches towards the bottom of the vessel for releasing beverages and a liquid viewing gage connects from the interior liner reservoir to the external vessel and rests above the controlled dispensing device to show the amount of liquid inside the interior reservoir.

The present embodiment of the removable filter apparatus and the interior liner provide the capacity to brew up to a gallon of tea or coffee using a gravity fed pour over brewing method for serving both large and small groups. Accordingly, the reader will see that one advantage of the device is the versatile brewing capacity makes it adept for different groups of people in diverse settings, such as, camping/rafting users, lodges, hotels, restaurants and office businesses, construction sites, boats, cafes, bars, and sporting events. The present embodiment of the device can utilize suitable alternative materials and configurations. In accordance with other embodiment, the device is designed to accommodate interior liners with brewing and insulating chamber capacities to suite the desired quantities of serving while in the backcountry, coffee shops, restaurants, or for home use. Advantageously, an alternative embodiment of the exterior vessel comprises of stainless steel making an attractive gravity fed pour over brewing device ideally suited for any coffee shop, cafes, restaurants, or other similar establishments.

Other advantages of one or more aspects of the device is that the filter apparatus has the capability to hold substantial amounts of brew mixtures for making larger quantities of brew liquids within one brew cycle than other pour over style coffee makers used for outdoor recreation. The filter apparatus contemplated in this embodiment is comprised of a durable porous mesh with a plurality of holes that allow liquids to flow through while retaining the brew materials. Advantageously, the filter apparatus is reusable allowing for extensive use without replacing, thus eliminating buying large quantities of single-use paper filters that must be thrown away or packed out of the backcountry for later disposal. Therefore, the filter apparatus embodiment is both economical and environmentally friendly.

The present embodiment of the device is made of materials that are extremely durable and temperature tolerant that reduces wearing and potential for replacement parts while providing ease of transport and use in rugged environments. Additionally, the device eliminates unnecessary components or fragile elements making the device practical for extensive outdoor and indoor use. Another beneficial aspect of the device's durability is that its components are all recessed and thus better protected from sheering or potentially breaking during use and transport.

Advantageously, the present embodiment may also be used for making cold brewed coffee by simply substituting cold water for hot water during the brew cycle. Traditionally, coffee shops drip-brew their coffee hot before adding ice to create iced coffee. This technique extracts acids from coffee beans creating a bitter tasting cup of cold coffee. The current embodiment's brewing method extracts less acid, thus creating a smoother and sweeter cold coffee. The portable brewing device also holds the cold brewed coffee in the interior reservoir at a colder temperature than the temperature outside the vessel. Additionally, users can add ice to the interior liner and keep any beverage iced for extended periods. Coffee shops can utilize the current embodiment's method for making tasty cold brew coffee for multiple customers at once.

Another advantage is the multifunctional aspects of the device wherein the device not only brews and insulates coffee and tea, but also serves an insulation vessel for other liquids like water, juices, and mixed beverages. Thus, the device serves as an all in one portable beverage insulator and brewing device. Another advantage of this embodiment is the vessel can be used for dry-storage of brew mixtures, cups, or other utensils while boating down the river, traveling by car, or other transportation means.
